[PATCH 1/2] completion: graduate out of contrib

[Felipe Contreras <felipe.contreras@gmail.com>]

These have been stable and widely used for quite a long time, they even
have tests outside of the contrib area, and most distributions ship
them, so they can be considered part of the core already.

We should be consistent and either we move the tests to contrib, or we
move the completions out of contrib.

Let's move them out of contrib and provide an installation target
install-extra.

By default bash-completion installs the completions to
$(pkgdatadir)/completions, which is
$(prefix)/share/bash-completion/completions. And since most distributions do
not change this, it is obviously the right default that distributions
can override with bashcompdir.

By default zsh looks for completions in
$(prefix)/share/zsh/site-functions.
